Warp-beam for looms



UNITED STATES PATENT OFFICE.

CHARLES A. DAYTON, OF ROCHESTER, NEW HAMPSHIRE.

wARP-BEAM FoR Looms.

SPECIFICATION forming part of Letters Patent No. 328,297, dated October 13, 1885.

Application filed April 15, 1884. Serial No. 127,996. (No model.)

To all whom it may concern: Be it known that I, CHAELEs A. DAYTON,-

a citizen of the United States, residing at Rochester, in the county of Stratford and State of New Hampshire, have invented certain new and useful Improvements in Warp-Beams for Looms; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure l of the drawings is a top view of a warp-beam constructed according to my invention. Fig. 2 is a vertical sectional view of the same, and Fig. 3 is a transverse section thereof.

This invention has relation to warp-beams; and it consists in the construction and novel arrangement and adaptation of parts, as will be hereinafter more fully set forth, and particularly pointed out in the claim appended.

In the accompanying drawings, the letter A designates the warp-beam body, on which the yarn is laid to be paid out in the weaving. B B are its journals, and C C the friction-pulleys on its ends.

Along each end portion of the beam are secured in longitudinal recesses of sufficient depth the threaded strips D, of metal, usually four in number, to each end of the beam, arranged on the quarters and in such relation that their threads will correspond to engage the full thread in the hub of the fiange E. The threads of these strips are formed obliquely across their width, so that the strips act conjointly like a screw for the reception of the threads in the hub of the said flange E. The depth of each recess F is such that the plate or base of the strip is inlet into the wood of the beam, the threads only projecting above its surface, as shown.

Between the strips D the surface of the beam appears at the full radialdistance from the axis of said beam, as shown at G. This construction is designed to avoid breaking the interior layers of yarn or thread, as well as to preserve the full strength of the beam as far as possible. The guard-flanges E are circular in form, and have the internally-threaded hubs H, which, when said anges are placed on the end portionsof the beam, engage the projecting threads of the strips D,which hold the anges plumb and prevent them from slipping endwise on the beam. The flanges E E are each constructed in two sections, as shown, and the adjacent radial arms a of the two halves or sections of each respective ange E are provided with transverse perforations, so arranged as to communicate with each other, as shown, and these h'alves or sections are connected together by means of bolts b and nuts c, the bolts being passed through the said perforations. The yarn being wound on the beam between these flanges serves to keep them from rotating by its frictional contact. frequently adjusted with reference to their distance from each other-sometimes as often as a new piece is made in the loom-and by the construction herein described this adjustment can be made with great facility and without loss of valuable time by simply rotating the flanges on the threaded strips in the desired direction.

As the flanges do not require to be clamped on the beam, they are subject to no strain.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-

The improved warp-beam body herein described, having its opposite ends provided with longitudinal recesses F, arranged at intervals circumferentially thereof, combined with the obliquely-threaded strips secured in the respective recesses, so as to sit slightly above the surface of the beam, the sectional flanges E, having their hubs provided with internal threads to engage the said threaded strips, and formed with radial arms a, having perforations, the bolts and nuts for connecting the sections of the flanges, and the pulleys secured to the opposite ends of the said beam, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES A. DAYTON.
